  6. Calculated and Observed Ozone Trends SAGE-I 1979-1981 and SAGE-II 1984-2000 Rolando Garcia • Red inset on left covers approximately same region as observations on right • Agreement is quite good, including region of apparent “self-healing” in lower tropical stratosphere

  7. Calculated and Observed Temperature Trends SSU + MSU 1979-1998 Rolando Garcia • Red inset on left covers approximately same region as observations on right • Note comparable modeled vs. observed trend in upper stratosphere, although model trend is somewhat smaller

  8. 4 K 100 km -2 K 3 K 80 km -2 K 3 K 50 km -3 K 0.8 K 25 km -0.8 K Calculated Temperature Trends, 1950-2003 Global-means, deseasonalized Caution: 11-year solar signal not removed in trend calculations; this is large above 50 km, as shown on right
